Description
PX4 Autopilot contains a heap buffer overflow vulnerability in the sd_bench command that writes a four-byte block number into a user-supplied sized allocation. Attackers can invoke sd_bench with a block size below four bytes to overflow the heap buffer and potentially execute code or crash the system.
